Noun: A disorder characterized by uncontrollable attacks of sleep during reading.

Tedious reads such as textbooks, contracts, and emails from your friend about how the ex is still jerking him/her around seven months later often bring on the nodding, blinking, and eventual unconscious state attributed to individuals suffering from this disorder. In severe cases, attacks may occur during good reads.

WARNING: If you fall asleep during common activities such as urinating, driving, and making toast, you may be suffering from narcolepsy or inebriation. Or you could just need more sleep. Please consult a physician before reading further.
